IPC: B22D11/10
Filed: 1996-08-16
Abstract: Thin metal strips, for example wide carbon steel strips, are cast in a single belt machine. The width of the molten metal on the belt is defined by side dams (12, 13) on the belt (11). The side dams have inwardly directed surfaces against the molten metal which makes the surface of the molten metal even also at its edges.

Title: Screw threaded fastener and fastening system
Inventor: ROBERTS DAVID JAMES ALEXANDER
IPC: F16B25/00
Filed: 1998-02-03
Abstract: A screw threaded fastener (103) has an elongate shank (122) with a drilling tip (104) at one end and a head (123) at the other end. A screw thread extends along at least a part of the length of the shank. The trailing flank (116) of the thread subtends an angle relative to the axis of the fastener which approaches 90° and is greater than the angle subtended by the leading flank (115). The screw is for use in fixing sheets of material to thin metal battens (5) and the angle between the trailing flank (116) and the adjacent thin metal section (18) of the batten, being reduced in comparison to a conventional thread form, lessens the distorting effect of the thread on the batten under relatively high pull-out loads.

Inventor: WECHSLER LAWRENCE I
IPC: A01K39/012
Filed: 1998-03-10
Abstract: In a feeder for dispensing flowable feed material, such as potable liquids and particulate solids, to birds and other animals, in which a hopper supplies such feed material to an access port in a feeding station positioned below the hopper, a refilling feature permits facilitated replacement of feed stock, as necessary. A hopper, for example a feed containing reservoir, is mountably receivable on a feeder support structure, which, while mounted thereto, is pivotable between an inverted position, in which an opening therein is appropriately located to permit outflow of feed therethrough while actively providing feed material to the feeding station for animal access, and another position in which the reservoir opening is oriented to prevent outflow of feed, thereby permitting removal of the reservoir from the feeder for refilling, or replacement thereof with a pre-filled replacement reservoir, without significantspillage of the contents. A feeder incorporating such feature advantageously includes mounting structure to facilitate mountable reception of same on a cage, or outdoor tree or other support, such mounting structure being disposed as not to impede the mounted movement of the feed reservoir.

Patent CA-2240065-A1 (CA)
Inventor: YOUNG TERRILL ALAN
IPC: A47K10/42
Filed: 1996-11-27
Abstract: An improved method is disclosed for forming a strata of overlapping sheets (S1S3) suitable for use in a pop-up dispensing system. The sheets (S1, S3) are cut from ribbons (R31-R33) having at least one side edge which has a knee-like protrusion (11, 211) with the opposing side edge being either, substantially parallel to the longitudinal axis (L2) of the ribbon (R31), or having one or more knee-like protrusions (11, 211) formed on the opposing edge. The ribbons (R31-R33) are then phased so that the knee-like protrusion (11) on one edge aligns with either the essentially parallel edge of an adjoining ribbon or a knee-like protrusion (11) on the side edge of the adjoining ribbon. Phasing can be accomplished by either, aligning knee-like protrusions (11, 211) on the side edges of adjoining ribbons (R31, R32) or reversing the orientation of the side edges of alternating ribbons (R31-R33). After phasing, the ribbons (R31R33) are overlapped creating a series of predetermined areas of greatest overlap (14) adjoining areas of least overlap (12) such that successive ribbons (R31-R33) are bonded only by the interfacial interaction between ribbons (R31-R33). By overlapping multiple ribbons (R31-R33) in this manner a strata is formed which is then folded to interleave the ribbons (R31-R33). A resulting stack of interleaved ribbons (R31-R33) is cut to form blocks of individual interleaved sheets. The process can be accomplished manually or in a continuous production process.

Title: Metal to metal seal with a malleable metal ring
Inventor: KOHLMAN NICHOLAS
IPC: F16L23/16
Filed: 1998-08-18
Abstract: A metal to metal seal and a method of forming the same includes providing a pair of opposed clamping faces. Each of the clamping faces surround apertures. Seal grooves serve to widen each of the apertures. Each of the seal grooves have truncated angular corners. A malleable metal sealing ring is positioned in the seal grooves. The sealing ring has truncated angular outer edges complementary to the truncated angular corners in the seal grooves. The clamping faces are clamped together in face to face relation to energize the sealing ring.  The sealing ring has an enlarged inner diameter to create an deflectable edge at the truncated annular edges. The subsequent application of internal pressure serves to promote deflection of the metal sealing ring at the truncated angular edges and further energize the sealing ring.

Abstract: Methods and systems for analyzing multi-threaded programs are provided. The predisposed execution of multi-threaded programs is modified to cause and detect latent unsafe accesses to a resource, such as a memory location. It is first determined that unsynchronized accesses to a resource of interest are possible. When a thread requests to access the resource, the thread is suspended. A subsequent thread that accesses the resource awakens the suspended thread, thereby causing unsynchronized accesses to the resource that may produce unpredictable results. The unsynchronized accesses can be logged for viewing by a user.
